Embodiment 1

[0033] Such as Figure 1~2 Shown: the elevator emergency intercom system of this embodiment includes the car intercom switchboard (such as communication equipment such as microphones, walkie-talkies or microphones or intercoms connected to preamplifiers), duty room intercom switchboards (such as microphones, walkie-talkies, etc.) and other communication equipment), machine room terminals (such as machine room extensions, machine room switchboards, etc.), car top terminals, car bottom terminals, D / A conversion devices and power amplifiers; among the above-mentioned main components, refer to figure 1 : Between the car intercom switchboard and the duty room intercom switchboard, between the car intercom switchboard and the car top terminal, between the car intercom switchboard and the machine room terminal, and between the car intercom switchboard and the car bottom terminal, CAN bus transmission is adopted, and the power The amplifier is connected with the D / A conversion device ...

Embodiment 2

[0038] The elevator emergency intercom system of this embodiment includes a car intercom switchboard (such as a microphone, a walkie-talkie and other communication equipment or a device after a microphone or a walkie-talkie is connected to a preamplifier), a duty room intercom switchboard (such as a microphone, a walkie-talkie and other communication equipment) ), computer room terminals (such as computer room extensions, computer room switchboards, etc.), car top terminals, and car bottom terminals. Among the above-mentioned main components, based on optical fiber communication, the cost is small, the bandwidth is large, and the reliability is large. The emergency intercom system is easy to install and low in cost; it is stable and reliable, and there is no need to consider expanding the communication line for video intercom. Refer to Figure 6: When the signal conversion device of the elevator emergency intercom system is an optical signal conversion device, this When the car ...

Abstract

Disclosed is an elevator emergency system, comprising an elevator emergency intercom system and an elevator emergency rescue system. The elevator emergency intercom system is connected to the elevator emergency rescue system by means of a signal switch to control startup and shutdown of the elevator emergency rescue system. The elevator emergency intercom system comprises a car intercom switchboard, a duty room intercom switchboard, a machine room terminal, a car top terminal, and a car bottom terminal. The car intercom switchboard is integrated in a signal distortion-resistant system. The signal distortion-resistant system comprises a COP TFT multimedia platform. The elevator emergency intercom system can start the elevator emergency rescue system during an emergency alarm or intercom to perform emergency rescue, thereby guaranteeing passengers' safety.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator emergency system. Background technique [0002] Elevators are used more and more frequently in people's lives. With the development of science and technology, the number of high-rise buildings in cities continues to increase, and elevators are becoming more and more popular. When people enjoy the convenience brought by elevators, they also pay more attention to the safety of elevators. Elevators in many cities have been used for a long time now, and their power supply facilities are aging. Sometimes a sudden power failure will cause the elevator to stop during operation; similarly, a sudden interruption of the mains power will also cause the elevator to stop running. This kind of situation will cause panic among the people, and some passengers even reacted excessively——during the power outage, they opened the car door and climbed out, which caused a great safety h...
